How to unlock ZTE MF667?

[jb2016]

I would like to know a solution to unlock this USB modem.

This is the details I get after running dc-unlocker2client_1.00.1299

DC - Unlocker 2 Client 1.00.1299

Detecting modem :

selection :
manufacturer - ZTE modems
model - Auto detect (recommended)

Found Applications port COM4
Found Diagnostics port COM3

Found modem : MF190
Model : ZTE MF190
IMEI : 865xxxxxxxxxxxx
Firmware : BD_AIRTELMF667PADV1.0.0B03
Compile date / time : Mar 20 2014 21:50:04
Chipset : Qualcomm MSM8200A
NAND Flash : ESMT_FM6AD1G12A
SIM Lock status : Locked (Card Lock)

There is this discrepancy. In the product (USB modem), I see model no. MF667. But in DC client shows a different (MF190) model no.

It's ok. Can go ahead and unlock it.

Thank you.
So can I go ahead and do it with ZTEQualcommWriter_v16?
If I am going with ZTEQualcommWriter_v16, should I go with firmware MF190 or MF667?
Because it says model no is MF190 but in firmware version I see MF667 (check snap shot below)



The red underlined looks closer to my version. Can I go with the Airtel version but the firmware version is BD_AIRTELMF667PADV1.0.0B02? ( mine is BD_AIRTELMF667PADV1.0.0B03)



And is there a way to backup the original I may need it if I brick the USB in the process of unlocking?

If you want to unlock it then use DC-unlocker client not flasher. You should know also that flashing is risky and may damage device which we won't be able to help repair, credits lost in flashing process also could not be returned or refunded.
